Patented .lune 3, 193@ UNITED STATES PATENT OFFICE ,WILLIAM SCHWALGE, 0F ELIVIHURST, ILLINOIS VULCANIZER FOR AUTOMOBILE TIRES Applcatonyled March 29, 1928. Serial No.726'5,708.

This invention relates'tovulcanizer for automobile tires and the like and is fully described in the following specification and shown in the accompanying drawings, in Which- Figure 1 is an end elevation of the device tour of the outer surface or, trie automobile' casinor A, which is shown in cross section ll/Tithin the tire A is placed a metal shoe 12 which is lhollow and preterably made oi cast iron. Between the shoe 3 2 and the tire A is placed a cushion 13 of storage rubber or the like. By using cushions of diiierentthicknesses, tires of various f sizes may be vulcanized in a single vulcanizer.

The section 11 is provided'at each end with a iieinble member 1eV Which is secured thereto, this end extending over the ledge 10:L on the section 10. The lower end of the flexible member 141- is provided with an eyelet 14 which is adapted to fit over the hooked end of the yolre 15.

The member 10 is likewise provided with a similar dexible member 16 which has an leyelet 16:l which engages a hooi; on the opposite end of th yoke 15. rl`his `yoke is tapped to receive a cap screw 17 lWhich is adapted to bear on the'undei side of the shoe 12.

Thus, itivill be seen that by tightening the s'crew 17 in the yoke 15 at each end of the vulcanizer, the shoe 12 is forced up into the vulcanizer, thereby compressing the tire A firmly between the shoe and the vulcanizer sections 10 and 11. At the same time, the pull on the flexible members 111 and 16 draws the tivo vulcanizer sections 10 and 11 together.

The section 11 is provided with an electrical heating element 18 Which is connected to a suitable terminal 19 which, in turn, is

adapted to be connected to a suitable sourceV of electrical energy. Leads 20 and 21 (Fig. -3) are also connected to the terminal 19 and these are connected to suitable' contact members `22 which are carried by insulators 28. .The contact member 22 iits into a suitable metal socketl 24 which is connected in series with the heating element 26. A similar set of'contacts 27 is providedat the opposite end' by which current is returned to the terminal 19through the lead 20.

Thus, it will be seen that I have provided a very simple and eiiicient form of vulca- Yniver which can readily be placed over an automobile tire 4and firmly secured thereon during the vulcanizing process by the simple act of tightening the two cap screws 17.

lllhile l have shown` and described but a single embodiment of this iiwention, it is to be understood that it is capable of many modiiications. Changes therefore in the construction and arrangement may be made which do not depart from the spirit and scope of the invention as disclosed in the appended claim.

l claim:

ln a vulcunizer for automobile tires, a casing made up 'of tivo sections adapted to fit around an automobile tire, a shoe adapted to conform to the inner surfacey of said tire, means in sait sections for heating them` iieniblemembers secured to each section and passing around the other, and means for tensioning these member and simultaneouslyT pressing said shoe inwardly toward said sections. i

In testimony whereof7 I have hereunto set my hand this 15th day otFebruary, A. D.,

WILLIAM SCHWALGE.
